Renowned in the disciplines of political theory and philosophy, Hannah Arendt's searing critiques of modernity continue to resonate in other fields of thought decades after she wrote them. In Communication Ethics in Dark Times: Hannah Arendt's Rhetoric of Warning and Hope, author Ronald C. Arnett offers a groundbreaking examination of fifteen of Arendt's major scholarly works, considering the German writer's contributions to the areas of rhetoric and communication ethics for the first time. Arnett focuses on Arendt's use of the phrase 'dark times' to describe the mistakes of modernity, defined by Arendt as the post-Enlightenment social conditions, discourses, and processes ruled by principles of efficiency, progress, and individual autonomy. These principles, Arendt argues, have led humanity down a path of folly, banality, and hubris. Throughout his interpretive evaluation, Arnett illuminates the implications of Arendt's persistent metaphor of 'dark times' and engages the question, How might communication ethics counter the tenets of dark times and their consequences? A compelling study of Hannah Arendt's most noteworthy works and their connections to the fields of rhetoric and communication ethics, Communication Ethics in Dark Times provides an illuminating introduction for students and scholars of communication ethics and rhetoric, and a tool with which experts may discover new insights, connections, and applications to these fields.
